A study has revealed that sunbathe is good for men as it improves the quality of sperm. Sun light is the largest source of vitamin D and it is vitamin D which regulates better sperm in men. The study was conducted by the researchers at the University of Copenhagen.

For the study, researchers tested the quality of sperm from 340 men and found that almost half had an insufficient amount which they linked to lack of exposure to natural sunlight or time in a solarium. The experts have advised would-be-fathers to spend more time in the sunlight.

While studying the sperm of 340 men, the researchers found that the quality of sperm was improved when they were exposed in the sun. Besides that, they become better at swimming towards the egg, showed greater speed and were more penetrative. Dr. Martin Blomberg Jensen, the author of the study said, “There was a positive link between higher levels of vitamin D and sperm movement”.

The findings of the study were published in the journal Human Reproduction. The study supports previous research in which vitamin D was linked to sperm production. It is believed that the study will help in understanding the reason behind why many couples seem to conceive on holiday.
